The US actor posted: “I am severely disappointed in myself at the insensitivity of my remarks that day.

“I know my sincerest apology now won’t take away those hurtful words. Rape and sexual harassment can reach anyone and I have seen first hand its painful torment among members of my own family and friends.

“I made a truly tasteless comment. It is unacceptable and I sincerely apologise with a heavy heart for the words I said.”
